Optical and chemical properties of As-Se and As-S-Se solution processed thin films prepared via As50Se50 source solution modification

Popis výsledku v původním jazyce

This work presents the prospect of As-S-Se and As-Se thin film preparation from a modified solution of As50Se50 chalcogenide glass in ethylenediamine. The source solution was modified by direct dissolution of elemental sulfur and amorphous elemental selenium. Using this method, we successfully prepared four sulfur-modified (As(4)5S(10)Se(45), As40S20Se40, As35S30Se35, and As30S40Se30) and four selenium-modified (As45Se55, As40Se60, As35Se65, and As30Se70) solutions. Thin films of all compositions (including unmodified As50Se50) were deposited in specular optical quality using spin coating. The structure, composition, organic residue content, refractive index, optical band gap, surface roughness, and chemical resistance of thin films were studied depending on the annealing temperature. The obtained data suggest the incorporation of both sulfur and selenium into the glass structure already in the solution, which resulted in changes of the optical and chemical properties of thin films. According to our observation both composition and proximity to stoichiometric composition have a major impact on the optical and chemical properties of the studied thin films. The solution modification allows easy preparation of thin films with multiple different compositions from a single source solution.
